Sapphire, a variety of corundum, is an allochromatic gemstone. "Allochromatic" means that in it's purest form it is colorless, however, the introduction of trace elements (also known as impurities) will cause it to take on just about any color in the rainbow. Sapphire can be yellow, orange, violet, pink, etc. The only color sapphire can NOT be is red - when corundum is red we call it "ruby". The blue-hued variety of the stone credits its magnificent color to a titanium impurity and is the benchmark against which all other blue gemstones are measured. This phenomenal 1940s trilogy ring made in platinum and 18k white gold features a 3.21ct rectangular step cut sapphire flanked by old European cut diamonds. This vibrant basaltic sapphire is untreated (which is uncommon, 95% of sapphires on the market have been treated in some way - usually by heat - to improve the visual quality of the stones), and the diamonds weigh in at .50ct and .52ct both graded as G-H/SI2. The three stones that comprise a trilogy ring are meant to represent the past, present, and future of a romantic union. This ring comes with an EGL certificate and appraisal for all stones.
ART DECO (1915 – 1940)
Art Deco is highly recognizable for its minimalism and futurism. Simultaneous art movements—Cubism, Bauhaus—informed the geometric style, along with “exotic” foreign influences like the Ballet Russe. Motifs like ziggurats and sunbursts, stripped of visual clutter, conveyed the optimism of an increasingly technological world.
In jewelry, the predominant use of white metals let colorful gems take center stage. Stones that were opaque and true in color, like lapis lazuli, onyx, jade, coral, and opal were worked into designs alongside more precious and brilliant gems, like diamonds, sapphires, rubies, and emeralds. Extra-long beaded necklaces and tasseled “sautoirs” followed the narrow flapper silhouette.
The baguette cut was an Art Deco innovation, and the decade saw increased use of other angular diamond cuts, like the precise caliber cut and the emerald cut. Synthetic gems, like sapphires, were celebrated as a scientific marvel. Marcel Tolkowsky, 21 years old at the time, published the design for the round brilliant cut in 1919.
